Question

Please help me and show steps

Answer 1

`\frac{ {x}^( - 1) + {y}^( - 1) }{ {(x + y)}^( - 1) } \\ \\ \frac{ (1)/(x) + (1)/(y) }{ {(x + y)}^( - 1) } \\ \\ \frac{ (1)/(x) * (y)/(y) + (1)/(y) * (x)/(x) }{ {(x + y)}^( - 1) } \\ \\ \frac{ (y)/(xy) + (x)/(xy) }{ {(x + y)}^( - 1) } \\ \\ \frac{ (y + x)/(xy) }{ {(x + y)}^( - 1) } \\ \\ (y + x)/(xy) / {(x + y)}^( - 1) \\ \\ (y + x)/(xy) / (1)/((x + y)) \\ \\ (y + x)/(xy) * (x + y) \\ \\ = \frac{ {(x + y)}^(2) }{xy}`

I hope I helped you^_^

Answer 2
